🧾 About

Tagline — One sentence describing what the extension does.

2–3 sentences: what problem it solves in the browser, who it's for, and what it replaces or improves.

Example:

Extension Name adds a persistent sidebar to any GitHub repository page that shows the full folder tree and lets you jump to any file with a keyboard shortcut — no more clicking through nested directories one folder at a time.
